Description

Technical Field

[0001] The utility model relates to the technical field of nutter ring production, in particular to a mold for producing nutter ring fillers. Background Art

[0002] Nate ring packing is a commonly used packing with a wide range of applications. Nate ring packing is a packing shaped like a ring and a saddle. It is a ring-saddle type packing with side wall openings made by stamping thin plates. There is a flange reinforcement rib with several circular holes on the back of the saddle. There are two semicircular rings on both sides of the rib that are opposite to the saddle. The diameters of the semicircular rings are large and small, and there is a flange on each side of the saddle. Nate ring packing has the advantages of low pressure drop, large flux and high efficiency.

[0003] The existing patent (Announcement No.: CN216461191U) discloses a mold for producing nate ring fillers, including an upper mold, a middle mold, a lower mold, a punching station, a rib cutting station, a profiling station, and a molding station. The upper mold, the middle mold, and the lower mold are distributed sequentially from top to bottom. By arranging the punching station, the rib cutting station, the profiling station, and the molding station on the lower mold in sequence, the mold can be continuously stamped, thereby improving production efficiency; the setting of the guide rod makes it difficult for the upper mold and the lower mold to deflect when moving, thereby ensuring the quality of the product. In the process of implementing this solution, it was found that the following problems exist in the prior art, which have not been well solved: the above-mentioned device allows the mold to be continuously stamped by setting different stations. When different types of workpieces need to be stamped, the mold needs to be disassembled and replaced, and the above-mentioned device needs to disassemble more materials when disassembling the mold, which results in a slower speed when processing different workpieces. Utility Model Content
